    Abstract: A multi-stream solid-state device (SSD) includes a normal-access memory associated with a first stream ID, a high-access memory having a higher endurance than the normal-access memory and being associated with a second stream ID, a controller processor, and a processor memory coupled to the controller processor, wherein the processor memory has stored thereon instructions that, when executed by the controller processor, cause the controller processor to perform identifying a data stream ID of an input data stream as one of the first and second stream IDs, in response to identifying the data stream ID as the first stream ID, storing the input data stream in the normal-access memory, and in response to identifying the data stream ID as the second stream ID, storing the input data stream in the high-access memory.

    Abstract: A storage device is disclosed. The storage device may include storage for data. A host interface logic may receive a dataset and a logical address from a host. A stream assignment logic may assign a stream identifier (ID) to a compressed dataset based on a compression characteristic of the compressed dataset. The stream ID may be one of at least two stream IDs; the compressed dataset may be determined based on the dataset. A logical-to-physical translation layer may map the logical address to a physical address in the storage. A controller may store the compressed dataset at the physical address using the stream ID.

    Abstract: A Solid State Drive (SSD) is disclosed. The SSD may include flash memory to store data and may support a plurality of device streams. A SSD controller may manage reading and writing data to the flash memory, and may store a submission queue and a chunk-to-stream mapper. A flash translation layer may include a receiver to receive a write command, an LBA mapper to map an LBA to a chunk identifier (ID), stream selection logic to select a stream ID based on the chunk ID, a stream ID adder to add the stream ID to the write command, a queuer to place the chunk ID in the submission queue, and background logic to update the chunk-to-stream mapper after the chunk ID is removed from the submission queue.
